I’ve wondered the same, about both.
Some here have stated that Sessions cannot un-recuse himself.
Why, I don’t know....maybe those familiar with applicable specific rules/laws can explain.
Sessions should at least resign as he has to see that what Mueller is doing is a coup and that it's his fault for recussing himself. So he wants the coup to go on or doesn't care about this injustice. Sessions is the same as all of the corrupt politicians.
Trump is the only one that is on the American people's side and that is trying to MAGA. The others either are leftists or just want to enrich themselves and couldn't care less about the American people ,America or Trump.
